[KDE4] kded4 chrashing on startup

OdinEidolon · 2011-05-22 07:36:05

Hi all!
Yesterday I updated the system and today in the morning I found that kded4 is crashing about 20 seconds after startup.
This is the backtrace:

Application: Demone KDE (kdeinit4), signal: Segmentation fault

This happens if I run kded4 via terminal then, it crashes after about 15-20 seconds: (this is of course only the end of the terminal output)

[2011-05-21 19:02] 1. To make plymouth work, add 'plymouth' to HOOKS after 'base' and
[2011-05-21 19:02]    'udev', and add 'quiet splash' to the grub command line, and 
[2011-05-21 19:02]    rebuild your initrd image.
[2011-05-21 19:02] 
[2011-05-21 19:02] 2. To enable encryption in plymouth, replace "encrypt" with 
[2011-05-21 19:02]    "plymouth-encrypt" in mkinitcpio.conf and then rebuild your
[2011-05-21 19:02]    initrd image.
[2011-05-21 19:02] 
[2011-05-21 19:02] 3. You will also need to rebuild your initrd image after change theme.
[2011-05-21 19:02]    
[2011-05-21 19:02]    To rebuild initrd image:
[2011-05-21 19:02]        mkinitcpio -p kernel26
[2011-05-21 19:02]    To change plymouth theme:
[2011-05-21 19:02]        plymouth-set-default-theme <theme>
[2011-05-21 19:02]    Do them together:

I searched using google and the forums but did not find anything recently related, and I have absolutely no idea on how to fix this

removing .kde4 does not help at all.

If you were using kde-unstable then I have some bad news for ya.

I don't. As you can see from the pacman.log file I posted there's nothing recently upgraded regarding KDE

OdinEidolon · 2011-05-23 18:36:02

Creating a new user does not do any difference.

hermes · 2011-05-25 08:06:56

The same happens here... I've just upgraded kdelibs, kdebase-workspace and kdeplasma-applets-networkmanagement and I get the same errors. Downgrading kdeplasma-applets-networkmanagement, plasma started to work again, but "Enable wireless network" in nm was grayed out. Downgrading kdebase-workspace as well made nm work again. I'm using brcm80211 drivers on a Broadcom BCM43225 wireless card.

OdinEidolon · 2011-05-25 08:17:51

Just to clarify, plasma works wonderfully for me actually, only KDED crashes. What bugs me is why this started happening. I didn't do anything tothe system and updates do not have anything to do with KDE IMHO.

supercow · 2011-05-29 20:22:38

I have a similar crash problem with same message with Amarok, Kdenlive...I think latest KDE update (4.6.3) is messed up...

I removed kchildlock and solved the problem.
Then the same happened with networkmanager, that removed everything's fine
